Project Idea: Perl 6 Syntax Explainer

Hi,
considering the vast number of Operators and the like, I had the idea to
implement a tool where you can enter a small piece of p6 syntax, and it
explains what that might mean. (like a perldoc -f for operators/syntax
elements instead of functions)
A short example:
$ p6explain '[]'
[...] can be
* '[$expression]': access to one or more array elements if used as
postcircumfix
Example: @a[2]; # access the third element of an array @a
* '[$operator]': the 'reduce' hyper operator
Example: [+] (1, 2, 3); # gives 1 + 2 + 3 == 6
In a regex/rule:
* '[$subregex]': groups the content of the brackets without
capturing the match result of $subregex
$ p6explain '*'
* can be
* '$exp1 * $epx2' the multiplication operator, forces numerical
context onto its arguments.
Example: say 2 * 3;
* 'multi sub *method_name' exports the sub method_name into the
global namespace
In a regex/rule:
* '$subregex*' is a quantifier meaning that the previous subregex
may be repeated an arbitrary number of times, including zero
times.
Example: m/ [ab]* / matches '', 'ab', 'abab', 'ababab'
# END OF EXAMPLE
I have a few requirements in mind (not necessarily sorted by importance):
* Free software: Artistic License 2, some BSDish or GPLish - I don't
mind, as long as it's free ;)
* Multiple frontends: I'd like to have at least a command line and a
web frontend
* Support for multiple (natural) languages.
* Perhaps support for other programming languages as well
* Should contain links/references to the official docs
Now I'd like to hear your opinion:
* Anything else that should go into the requirements?
* Is it useful at all?
* Is it possible to implement it satisfactory without building a p6
compiler?
* Do you have a good idea for a project name?
Any other ideas and comments are welcome as well.
Cheers,
Moritz
